upload image into two folders help!

i am wondering where i am going wrong, i have a uploader image in php and html, it all works as in it goes into the set folder, but i have a problem, because i want the program to do the folder then do another folder inside,as in using the id of the litter which comes from the database.
i want to split this up into litterid as then i would know where to relocate the images, otherwise there will be a huge mixup from people uploading and no real details of where it needs to go.

i been using the get information and it doesnt seem to work as i hoped, plus i have three coded phps, one which is the form, another is the process and last one is sucess of the whole image uploading!

<?php
$litterid= $_GET ['litterid'];
// filename: upload.processor.php
// first let's set some variables
// make a note of the current working directory, relative to root.
$directory_self = str_replace(basename($_SERVER['PHP_SELF']), '', $_SERVER['PHP_SELF']);
// make a note of the directory that will recieve the uploaded files
$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'puppypictures/".$_GET ["$litterid"]."/';
// make a note of the location of the upload form in case we need it
$uploadForm = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'multiple.upload.form.php';
// make a note of the location of the success page
$uploadSuccess = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'multiple.upload.success.php';
// name of the fieldname used for the file in the HTML form
$fieldname = 'file';
//echo'<pre>';print_r($_FILES);exit;
// Now let's deal with the uploaded files
// possible PHP upload errors
$errors = array(1 => 'php.ini max file size exceeded',
2 => 'html form max file size exceeded',
3 => 'file upload was only partial',
4 => 'no file was attached');
// check the upload form was actually submitted else print form
isset($_POST['submit'])
or error('the upload form is neaded', $uploadForm);
// check if any files were uploaded and if
// so store the active $_FILES array keys
$active_keys = array();
foreach($_FILES[$fieldname]['name'] as $key => $filename)
{
if(!empty($filename))
{
$active_keys[] = $key;
}
}
// check at least one file was uploaded
count($active_keys)
or error('No files were uploaded', $uploadForm);
// check for standard uploading errors
foreach($active_keys as $key)
{
($_FILES[$fieldname]['error'][$key] == 0)
or error($_FILES[$fieldname]['tmp_name'][$key].': '.$errors[$_FILES[$fieldname]['error'][$key]], $uploadForm);
}
// check that the file we are working on really was an HTTP upload
foreach($active_keys as $key)
{
@is_uploaded_file($_FILES[$fieldname]['tmp_name'][$key])
or error($_FILES[$fieldname]['tmp_name'][$key].' not an HTTP upload', $uploadForm);
}
// validation... since this is an image upload script we
// should run a check to make sure the upload is an image
foreach($active_keys as $key)
{
@getimagesize($_FILES[$fieldname]['tmp_name'][$key])
or error($_FILES[$fieldname]['tmp_name'][$key].' not an image', $uploadForm);
}
// make a unique filename for the uploaded file and check it is
// not taken... if it is keep trying until we find a vacant one
foreach($active_keys as $key)
{
$now = time();
while(file_exists($uploadFilename[$key] = $uploadsDirectory.$now.'-'.$_FILES[$fieldname]['name'][$key]))
{
$now++;
}
}
// now let's move the file to its final and allocate it with the new filename
foreach($active_keys as $key)
{
@move_uploaded_file($_FILES[$fieldname]['tmp_name'][$key], $uploadFilename[$key])
or error('receiving directory insuffiecient permission', $uploadForm);
}
// If you got this far, everything has worked and the file has been successfully saved.
// We are now going to redirect the client to the success page.
header('Location: ' . $uploadSuccess);
// make an error handler which will be used if the upload fails
function error($error, $location, $seconds = 5)
{
header("Refresh: $seconds; URL=\"$location\"");
